About Us
Twilight Physician Group
Twilight Physician Group is a non-profit primary care that was started in 2022 after noticing a major health gap in the older population. Our providers were tired of those 15 to 20 minute patient visits that obviously needed more time. They became providers to provide quality healthcare, not to provide a quantity of visits. Twilight Care, now known as Twilight Physician Group, started with a vision of going to the private residences of their patients to provide them with top-quality care that was also affordable for them and their families. And we aren't stopping there. We are making our goal to reach homes in all of New Mexico, no matter how rural or remote. Please follow us, as we continue to grow with our local communities.

Patient & Professional Testimonials
Nathan Gabaldon, AA, NCG, COO Integrative Clinical & Financial Services, LLC.
Twilight, Sol Amor Senior Care, & Luna Del Valle Hospice:
I have been working as a professional fiduciary since 2014 and over the years trying to find knowledgeable, caring, thorough, and responsive providers has always been a struggle. I have personally worked with just about every medical provider, home care agency, and hospice service in the greater Albuquerque area. My introduction to these organizations began through Twilight Physician Group and expanded thereafter following notice that they would be adding additional supportive services. Since finding these three organizations, I have been able to ensure that my clients are cared for by responsive and caring providers. Through their endeavors to expand services, they have demonstrated an ability to provide continuity of care through medical support, in-home caregiving services and, when appropriate, hospice care. In this post pandemic world, as organizations continue to struggle with staffing issues and employee turnover, Twilight Physician Group, Sol Amor Senior Care, and Luna Del Valle Hospice appear to have found reliability in their hiring practices. As a professional fiduciary, consistency and reliability are paramount in my continued support of my clients. These teams are Albuquerque’s best kept secret in the field of aging and elderly care. Whenever possible, I work diligently to facilitate their involvement with my clients. Five Stars is an inadequate formula to rate these fantastic organizations as their care, attention, and consistency with persons served is second to none.
